Abstract-This paper presents many technical issues and shortcomings confronted in installation of micro-grids particularly in rural areas. It discusses the technical challenges involved in grid integration of micro-grids and highlights some aspects of stability in micro-grids. There are different types of micro-grid applications. The system layout and the control design vary depending on the application and so does the facet of stability in a micro-grid. It briefly encompasses the stability aspects of remote, utility connected micro-grids depending on the modes of operation, control topology, types of renewables and the network parameters. In the end, a brief insight into IEC 62257 specifications has been given.Index Terms-Power quality, smart grid, solar power, stability, wind power.

“…It should be noted that O/C elements are coordinated considering the presence of DGs [15]. Moreover, in addition to distribution feeders with high penetration of DGs, this method can be applied to collector grid of wind-power plants [71].…”

“…The main drawback of these methods is respectively, preventing high penetration of DGs, additional cost for DGs, high investment cost, difficulty in control of the fault current, high computation burden, and high complexity. In addition, according to the complexity of the future grid, employing a directional overcurrent relay was suggested by [12] to deal with the problem of bidirectional power flow. However, this type of protective device is expensive and requires more complex coordination methods.…”
